We have started to work on recommissioning our Nissan 300ZX and get it ready for an upcoming MOT. The brakes caliper pistons are seized due to a seal on each being split. These will need to be overhauled as part of the recommission. The springs need to be replaced with new but at present we can only source 1 of 2 required. A lot of suppliers are still away from work so hopefully we can track down another soon. The top hoses have crystallised inside and this has been caused by the joint (pictured) having corroded over the years.
